Ewings sarcoma is a malignant mesenchymal tumor, extremely rare in patients under 10 years of age, being more frequent from the second decade of life. Its annual incidence is low, 1 to 3 cases per year per million children under 15 years of age. The most affected bone sites are: metaphysis of the long bones, Followed frequently by the pelvic bones from 20 to 25%, tumors that affect the axial skeleton have a worse prognosis and affect individuals close to adulthood. The symptoms are common to other bone tumors: intermittent pain and inflammation located in the affected area, and metastases via the hematogenous route to the lung. It appears in patients in the stage of life of greater exercise and changes in the body typical of adolescence. Treatment is based on extensive surgery of the lesion with free section margins whenever the site or location of the tumor allows it, chemotherapy with high-dose drug association, and radiotherapy. More than 90% of these tumors are characterized by a reciprocal translocation of chromosomes 11 and 22, resulting in a novel EWS-FLI1 fusion protein. Because these tumors show only neuroectodermal markers of differentiation, it has been suggested that they arise from neural crest cellsf. Our goal is to present a case of a patient of only two years of age with stage IV disease at the time of diagnosis, highlighting the value of multidisciplinary teamwork where imaging studies and pathology immunohistochemical techniques play a fundamental role in the diagnosis of the entity.
